General Information

Storage

Temperature and time are key — the colder it is, the longer the best-by date. All brews are prepared fresh and flat upon delivery. Best-by dates depend entirely on how they're stored after delivery, since they are raw, living products that keep fermenting on their own.

Guidelines on storing raw Kombucha and Milk Kefir

  • Store cold at 2°C — food safety guidelines recommend fridges set to 2–4°C.
  • Gas build-up can occur rapidly if stored above 2–4°C (shown by distended caps).
  • Do not store in a wine chiller/wine room — these run ~10–15°C and cause rapid gas build-up.
  • Low pH keeps kombucha and kefir safe to consume even when fizzy — the organic acids create an environment unsuitable for harmful bacteria and mould.
  • If gassy or caps are distended: chill until very cold, then open with care at the sink (enclose in a plastic bag to be safe). Don't shake before opening.

Kombucha: up to 3 days at room temp (non-chia) · up to 1 week at 8–10°C · up to 2 weeks at 5–7°C · up to 6 weeks at 2–4°C (ideal). Freezing extends shelf life by months (may lighten in colour; nutrition unaffected).

Do not open chia-seed kombuchas with distended caps — without covering with a waterproof bag as they will spray. Even then, they are safe to consume.

Milk Kefir: stable 10–12 hours at room temp (chill ASAP) · up to 4 days at 8–10°C · up to 2 weeks at 5–7°C · up to 6 weeks at 2–4°C (ideal). Freezing extends shelf life by a few months but changes texture from thick to thin (blend to smoothen; nutrition/probiotics unaffected).

Craft & Culture is not liable for refunds or replacements for products not stored at the recommended temperatures post-delivery.

Natural Skin Care

Our skincare is made in small batches with natural preservatives (like fermentation bacteria, e.g. Lactobacillus). We don't encourage use beyond 12 months after purchase — check product containers/pages for specific use-by details.

Detox Reactions / Candida

Candida Die-Off Effects

If your gut health isn't optimal, starting kombucha or milk kefir may trigger "Candida Die-Off" (a Herxheimer reaction) — yeast cells die rapidly and release metabolic by-products, causing temporary symptoms. Severity varies by person; if symptoms are strong, reduce your serving.

Possible symptoms

  • Nausea, headache, fatigue, dizziness
  • Swollen glands, bloating, gas
  • Constipation or diarrhea (most common)
  • Joint or muscle pain, chills
  • Itchiness, hives, rashes, sweating, skin breakouts
  • Recurring yeast/vaginal/prostate/sinus infections
Stop consumption and seek medical attention immediately if you experience fevers, wheezing, elevated heart rate, itching/tingling around lips or mouth, swelling of lips/tongue/throat, or coughing/shortness of breath.

Coping with die-off

  • Reduce your daily intake and increase water intake to flush toxins faster.
  • then continue daily consumption to help the body accustom and rebalance over time.
  • If symptoms don't ease within a week of daily use, stop — you may be intolerant to compounds in fermented products (e.g. milk proteins, distinct from lactose intolerance).

Information provided is not intended to treat or diagnose medical conditions. Please use good judgement and seek medical attention if needed. Experimental benefits vary by individual.

Gift Options & Packing

All bottles arrive in reusable plastic bags. To gift our brews, we recommend ordering 15 x 250ml bottles and noting "gift box of 15" in your cart notes — a free gift box is available on request for every 15 bottles ordered. We're unable to provide gift boxes for smaller orders, or split boxes (e.g. 7 + 8 in two boxes).

Notes

Add a message in the Notes section at checkout and we'll include it — free birthday cards are also available.

Gift Cards

We also offer Gift Cards that can be redeemed any time, available on our Gift Cards product page.

Bottle Returns & Refills

(Until 30 Sept 2026 only) We accept bottle returns at our store and sanitize them with industrial-grade sanitizer before reuse. Bottles must be cleaned, dried, and left uncapped — wet, damp or dirty bottles with food/liquid residue will be discarded for food safety reasons.

  • Store drop-off: Leave bottles outside our store hanging on the door handle.
  • Delivery pickup: If you have an existing delivery order, message us first — we may be able to collect empty bottles, but can't make a dedicated trip without an existing order.

Are food-grade, BPA-free PET bottles safe to reuse?

Yes — PET has been extensively tested and is approved for single- and repeat-use as a drink container by the FDA, the European Food Safety Authority, Singapore SFA and other agencies worldwide, with no significant evidence of harmful chemical migration.

Exchange & Return Policy

All orders are strictly non-refundable once placed.
Extenuating circumstances are handled at the our staff's discretion — please contact us and we'll do our very best to help.

As our beverages contain live cultures, slight differences in taste and colour are normal. We generally do not exchange or refund for the following:

  • Tartness: everyone's tolerance differs — dilute with water (kombucha) or milk (kefir) to taste.
  • Colour differences: live bacteria activity varies batch to batch; taste stays consistent.
  • Bulging bottle/cap: normal sign of natural carbonation from live cultures, not spoilage. Chill well before opening; never shake or open at room temperature. Do not attempt to open heavily distended bottles or chia-seed kombucha with distended caps — without covering the caps with a waterproof bag as the chia seeds will spray.
  • Chia on the bottle exterior/neck: from hand-filling; not a leak or safety issue — simply shake to mix.
  • Overflow/gushing on opening: a sign storage was warmer than ideal, not a safety issue — open with care.
  • Consistency - thicker or thinner than preferred / used to (for kefir):
    In the case of kefir, the viscosity can vary between thick to thin (-ner than milk) from batch to batch or even within the same batch.
  • Separation into layers (for kefir): Pls see detailed FAQ below
  • Fizzy or flat brews: our brews are raw, unpasteurized, and intentionally prepared fresh and flat — outcome depends on storage.
  • Not experiencing expected benefits: our products are not medicine and aren't intended to diagnose or treat conditions; results vary by individual.

Skincare

We use natural materials and organic produce where possible. Please patch test and wait 24 hours before full application; discontinue and rinse with water if irritation occurs.

Delivery & Pickups

Delivery Access, Contact Attempts & Missed DeliveriesPlease read

To keep deliveries fair, timely and safe for every customer, our couriers follow a standard contact-and-drop protocol for every address. This applies equally to all customers and cannot be varied on a case-by-case basis at the doorstep.

What our couriers will do

  • Attempt to call and/or text you once, typically 5–30 minutes before arrival.
  • Ring the doorbell/intercom or knock once upon arrival.
  • If there is no answer within a reasonable window (a few minutes), leave your order at the agreed or most reasonable safe drop point (doorstep, front gate, or riser) and take a photo as proof of delivery — as set out in our delivery terms below.

What our couriers are not able to do

  • Wait at your address beyond a few minutes.
  • Make repeated phone calls or return later the same day to try again.
  • Hand-deliver into your hands as a matter of course — our standard protocol is a contactless doorstep/gate drop with photo proof, not an in-person handover, unless this has been explicitly pre-arranged with our team in writing/WhatsApp before the delivery day.
  • Enter private compounds, unlock gates, or wait for remote gate release beyond a single reasonable attempt.
If a delivery cannot be completed because a doorbell, phone, or gate goes unanswered, or because there is no accessible/safe spot to leave your order, this is treated as a failed delivery attempt due to the customer's unavailability — not an error on our part. Please see our redelivery fee policy below.

Your responsibility as the customer

  • Ensure someone is reasonably reachable by phone/text at the delivery window you selected, or provide clear advance instructions for an alternative drop point.
  • Ensure your address, unit number, and any gate/access codes are correct and provided ahead of time.
  • If you anticipate access difficulties (e.g. locked gate, guarded landed property, intercom issues), let us know at least one day in advance via WhatsApp so we can plan accordingly — this cannot be resolved at the point of delivery.

Redelivery & repeated failed attempts

Where a delivery fails due to no fault of ours (unanswered door/phone, inaccessible premises, incorrect address, or a customer insisting on terms outside our standard protocol), a redelivery fee applies for any further attempt, even for orders that originally qualified for free delivery. We reserve the right to require full prepayment of the redelivery fee before scheduling another attempt.

Customers with repeated failed delivery attempts, or who require couriers to deviate from the standard protocol above, may be moved to store pickup only for future orders, at our discretion.

Group Deliveries (Fri)

Group Deliveries are subsidized batch deliveries every Friday (or Thursday if Friday is a public holiday). Routes are set by proximity, so we're unable to accommodate specific timing requests for group delivery — personal courier via Grab/Lalamove is available if you need a set time. Estimated arrival window: 1100–2000, weather- and traffic-dependent. This can be narrowed down further on the day of delivery once drivers' routes are set — WhatsApp us on delivery day to request an ETA.

Group delivery costs (after promo prices, brews only)

  • $10 for orders below $65
  • $7 for orders $65–$107.90
  • Free for orders $108 and above

Orders with brews + workshops are fulfilled for pickup on the workshop date (workshop sign-ups don't count toward free delivery). Rates don't apply to Sentosa and Tuas — select delivery method accordingly.

What to expect

  • Order by Thursday 6pm for Friday delivery; later orders ship the following Friday (unless personal courier is arranged).
  • Non-beverage items ship via standard mail, typically 1–7 business days.
  • If you won't be home, let the courier know where to leave your order — a cooler bag/box is recommended, though brews are forgiving for a few hours unrefrigerated. Refrigerate as soon as you're back.
If no one signs for delivery and the order goes missing, Craft & Culture isn't liable for replacement. Please ensure your address (incl. unit number) is correct — last-minute address changes on delivery day can't be accommodated. Sentosa/Tuas deliveries require an additional delivery top-up added to cart before checkout.

Questions? WhatsApp us at +65 8591 6011.

Pick Ups (Mon–Fri, by appointment only)

As a production kitchen, we don't keep regular retail hours. Please WhatsApp 8591 6011 ahead to arrange your pickup.

Pickup days/times: Mon–Fri, 9am–1pm.

  • Minimum 6 bottles for online orders.
  • No pickups on public holidays, weekends, or outside these hours.
  • One-time reschedule allowed.
  • Please WhatsApp your pickup date/time within 2 weeks of ordering — no-shows/no communication after 2 weeks won't be replaced (all orders are strictly non-refundable).

Store Location

183 Jalan Pelikat, #B1-113, Singapore 537643 — between Lobby 3 and 4 of The Promenade @ Pelikat, a 5–10 min walk from Kovan MRT, beside Hougang Ave 1 Park. Parking is free for the first 10 minutes, then 3¢/min. We're open 24/7 for online orders.

Personal Delivery (WhatsApp for a quote)

For delivery Monday–Friday at a timing of your choice (1000–2000):

  • Give at least one day's advance notice (same-day may be possible — check with us first).
  • Add your preferred timing/day in the cart Notes section, select "Personal Courier" at checkout, then send us a WhatsApp confirmation at 8591 6011.
  • Our courier will call/text 5–30 minutes before arriving.
  • If you're not around, the order can be left at your doorstep/gate — a photo and signature are collected as proof of delivery.
  • Refrigerate as soon as you receive your order.
Please ensure your address (incl. unit number) is correct. Sentosa deliveries require an additional top-up (courier rates are roughly double). If we can't deliver due to no fault of ours, re-delivery charges apply; cancellations after dispatch incur delivery charges plus 50% of the order amount.
Delivery Partners (Mon–Fri)

We also partner with major online grocery platforms for weekday deliveries:

Postal Mail — Skincare / Cultures Only

For orders of cultures, skincare, or DIY kits (no brews), your order is prepared within 1–5 business days.

  • Pickup: confirm with us via phone/WhatsApp ahead of time.
  • Standard mail: via SingPost, typically 5–10 days; contact us if not received after 14 days.
  • Mail with tracking (recommended add-on): we'll email you a tracking code.

Orders combined with brews are fulfilled together via our Group Delivery service. Please ensure your address is correct — we're not liable for lost mail after posting if incorrect addresses were provided; tracked mail is highly recommended.

Helpful Info for Mums, Kids, Pets and on Eczema

For Mums & Kids

Can I take kombucha/kefir when pregnant?

If you were already taking probiotics before or during pregnancy, you may continue. If not, we recommend consulting a medical professional first.

Why probiotics can help mums & babies

Probiotic foods are considered beneficial for pregnant and nursing mothers, potentially helping prevent overgrowth of Group B Strep bacteria and supporting nutrient absorption, immunity, and hormonal adjustment. Nursing mums may also pass on benefits through breastfeeding.

Experimental benefits (may vary by individual)

  • Relieves allergies, supports skin health
  • Improves immune system
  • Tranquilizing effect on the nervous system (sleep, mood, focus)
  • Improves gut health and intestinal function
  • Regulates blood pH, detoxifies the liver, improves energy

Serving sizes for kids

Milk Kefir: 1–2 yrs: 4 tbsp · 2–3 yrs: ~60ml (1/4 bottle) · 3–5 yrs: ~120ml (1/2 bottle) · 5–7 yrs: 1 bottle (250ml)

Kombucha: 1yr+: ~60ml (1/4 bottle) · 3–5 yrs: ~120ml (1/2 bottle) · 5–7 yrs: 1 bottle (250ml)

Is kombucha's caffeine safe for kids?

Kombucha is brewed with black tea, but caffeine breaks down significantly over the ~4-week fermentation, resulting in low-to-negligible levels — generally considered child- and pet-friendly. Sugar content is roughly 2–4% by bottle volume.

Information provided is not intended to diagnose or treat medical conditions; benefits vary by individual.

Pets

Many pet diets are high in processed grains/carbs that break down into sugars, which can fuel yeast and skin issues. Milk Kefir and Kombucha can help support gut flora in pets too — Craft & Culture has served pet parents in Singapore since 2015.

Potential benefits for pets

  • Anti-biotic and anti-fungal properties
  • Supports digestive balance, especially after antibiotics
  • Allergy management, healthier-looking skin
  • May help with gas, bloating, and general digestive comfort

How much to feed

  • Small dogs/cats: 3 tbsp
  • Medium dogs/cats: 5 tbsp
  • Large dogs: 7 tbsp

Start with half the recommended dose for the first few days to a week to let your pet's system adjust, then build up gradually.

Serving suggestions

Try mixing kefir or kombucha with fruit (e.g. blueberries) as a treat or blended smoothie, rather than pouring over dry kibble.

Pet-friendly picks

Original Milk Kefir — just 2 ingredients (full cream milk + kefir cultures), no added sugar. Original Black Tea Kombucha — low caffeine after fermentation, ~5% sugar by volume.

Information provided is not intended to diagnose or treat medical conditions; benefits vary by individual.

Allergies & Eczema

Allergies affect roughly 20% of people in developed countries and arise from immune system hypersensitivity — including hayfever, food allergies, eczema (atopic dermatitis), allergic asthma, and anaphylaxis.

Research suggests probiotics may help manage some allergy conditions, since ~70% of the immune system is located in the gut. Studies have pointed to probiotics helping prevent eczema in genetically at-risk children, and supporting atopic dermatitis treatment.

A two-pronged approach

Internally (diet): avoid known trigger foods (consult your physician if unsure) and eat probiotic-rich foods like kefir, kombucha, kimchi, and miso.

Externally (lifestyle): reduce environmental allergens (dust mites, pollen, animal hair), wear natural fabrics, and use natural skincare products where possible.

Other experimental benefits of probiotics

  • Supports immune-related wellbeing
  • May support mood, sleep, and focus
  • Supports gut health and healthy cravings management
  • Regulates blood pH, supports liver detoxification, boosts energy

Information provided is not intended to diagnose or treat medical conditions; benefits vary by individual.

All experimental benefits listed on www.craftculturesg.com can vary from person to person. Our products are helpful for many but may have no effect on some. We do not provide guarantees of intended results post consumption of our products.

Refund / Return / Cancellation Policy

Cancellation: You may cancel your ala carte order within 24 hours of order via email only.

Subscription cancellation: Subscriptions can only be terminated after the 5th order cycle.

Beverages: As our beverages contain live cultures, please be aware that slight differences in colour and taste are possible, subject to our climate. Unless grossly misrepresented or errors were incurred on our part, all sales are final. That being said, please feel free to let us know if you have an issue and we'll be more than happy to resolve them.

Natural Skin Care Products: We use natural materials in all formulations and organic produce when possible. Before using our natural skin care products, please perform a patch test on your skin and wait 24 hours before full application. If any irritation occurs, rinse generously with water and discontinue use. We offer exchanges for all unused and unopened products and full refunds for all products that cause skin allergies when applied.

Pickup no-shows & last-minute cancellations: All orders are strictly non-refundable. No-shows (no communication of pickups by customer within 2 weeks of order / last-minute cancellations) are non-replaceable. Failure to communicate on a pickup appointment after 2 weeks will automatically fulfil the order. Requests for replacement or refunds will not be provided.

Pickup rescheduling: Craft & Culture permits a one-time reschedule of dates for pickups.

Non-deliveries resulting from recipient's actions: If the recipient is unable to receive the delivery in person or through a proxy in spite of several attempts to contact the recipient, the delivery will be placed in front of the doorstep or gate. In most but not all cases, a photo will be taken and sent to the recipient as proof of delivery. The products are prepared at room temperature and are forgiving at room temperature for several hours without refrigeration. No refunds or exchanges will be made.

NEW — Delivery access & conduct: "Several attempts to contact the recipient" means our standard single call/text plus a single doorbell/knock, as set out in our Delivery Access, Contact Attempts & Missed Deliveries FAQ above — not repeated calls, extended waiting, or an in-person handover. Recipients (or their proxies) must be reasonably reachable and premises reasonably accessible at the selected delivery window. Craft & Culture reserves the right to charge a redelivery fee, require store pickup only, suspend delivery services to, or decline future orders from any customer or address where: (a) delivery access requirements set out in these Terms are repeatedly not met; (b) a customer insists on delivery conduct outside our standard protocol; or (c) our staff or delivery partners are subjected to abusive, threatening, or harassing behaviour. This right may be exercised at Craft & Culture's sole discretion and is in addition to, not in place of, any other remedy available to us.

Refunds (if applicable): If you are approved, then your refund will be processed, and a credit will automatically be applied to your credit card or original method of payment, within 3–5 business days.

Late or missing refunds (if applicable): If you haven't received a refund yet, first check your bank account again. Then contact your credit card company — it may take some time before your refund is officially posted. Next, contact your bank, as there is often some processing time before a refund is posted. If you've done all of this and still have not received your refund, please contact us at support@craftculturesg.com.

Exchanges (if applicable): We only replace items if they are defective, damaged, or made in error on our part. Shipping costs are non-refundable — if you receive a refund, return shipping will be deducted from it. Time for an exchanged product to reach you may vary depending on location.

Allergy Policy

While we strive to provide a safe experience, Craft & Culture is not allergen-free — potential trigger foods may be present and served on premises.
Please inform us of dietary restrictions at checkout. We will endeavour to accommodate special requests where possible. Participating with a known allergy means agreeing to hold Craft & Culture harmless for any allergy-induced reaction. Anyone with anaphylaxis risk must bring their own treatment and be prepared to self-administer if required.

Children Policy

We host kids and young adults in classes specifically geared toward ages 12 and up. Kids under 12 must be accompanied by an adult, as we do not offer drop-off programming. Tweens and young adults are welcome to register for our regular classes.

Common FAQ's

I won't be at home in time for my delivery. What should I do?

Please plan ahead using one of these two options — this cannot be arranged with the courier at the point of delivery:

1. Let us know in advance where to leave your order

Our courier will call/text once, 5–30 minutes before arriving. If you're not home and don't answer, per our standard protocol your order will be left at your doorstep, front gate, or riser, with a photo sent to you as proof of delivery.

  • If you have a cooler box/bag, ask the courier to place the brews inside.
  • If not, no worries — our brews are fermented at room temperature and are forgiving unrefrigerated: Kombucha up to 3 days, Kefir up to 10–12 hours. Just refrigerate as soon as you're back.

2. Arrange a different time or pickup ahead of time

Message us at least a day in advance via WhatsApp (+65 8591 6011) to arrange a personal courier timing that works for you, or switch to store pickup (Mon–Fri, by appointment).

Our couriers follow one standard delivery protocol for every customer and are not able to wait, make repeated calls, or hand-deliver in person outside this protocol — see our Delivery Access, Contact Attempts & Missed Deliveries FAQ for full details.
What if I insist my order be handed to me personally, or that the courier keep calling/waiting at my convenience?Please read

We understand some customers would prefer an in-person handover, but for the safety and fairness of all customers on a delivery route, our couriers follow one consistent protocol (see above) and are not authorised to deviate from it at the doorstep — this includes waiting beyond a few minutes, making repeated calls, or personally handing over an order against standard procedure.

If a courier is asked to deviate from this protocol, they will politely decline and proceed according to our standard terms (leaving the order at a safe drop point with photo proof, or returning it if there is no safe/accessible drop point). This is not a decision made by the courier personally — it is company policy that applies equally to every address.

Customers who require different handling should arrange this with our team in advance (see "Personal Delivery" above) — not at the point of delivery.

 We reserve the right to charge redelivery fees, move a customer to pickup-only fulfilment, or decline future orders where this is not respected, or where our delivery staff are treated abusively or rudely.

See our full Terms & Policies above.

When / what time will my delivery arrive? When can I do a store pickup?

Group Delivery (Fri): estimated arrival window is 1100–2000, weather- and traffic-dependent. This can be narrowed down further on the day of delivery once drivers' routes are set — WhatsApp us on delivery day to request an ETA.

Personal Delivery (Mon–Fri, WhatsApp for a quote): arrives within your chosen window between 1000–2000. The courier will call/text 5–30 minutes before arriving.

Store Pickup: Mon–Fri, 9am–1pm, by appointment only — please WhatsApp +65 8591 6011 ahead of time to arrange a slot. No pickups on public holidays, weekends, or outside these hours.

May I get my deliveries/pickups at a specific (earlier/later) time and day (other than Friday)?

Yes, for more flexibility:

  • Personal Courier: choose your own day (Mon–Fri) and a timing window between 1000–2000 — WhatsApp us at least a day ahead to arrange.
  • Delivery Partners: order via Redmart/Lazada, Shopee, or FairPrice Online for Monday–Friday delivery on their own schedules.
  • Store Pickup: Mon–Fri, 9am–1pm, by appointment.

Group Delivery is fixed to Fridays (or Thursday if Friday is a public holiday) with no timing exceptions, as routes are set by proximity to keep costs low.

Do you provide ice packs/cooler bags/styrofoam boxes?

Our brews are prepared and stored in temperature-controlled conditions right up to delivery, and are stable at room temperature for several hours afterward — this is exactly why we're able to deliver without cold trucks or ice packs. As such, we don't provide ice packs, cooler bags, or styrofoam boxes as standard with delivery orders.

If you have your own cooler bag or box at home, you're welcome to instruct the courier to place your brews inside on arrival. Otherwise, simply refrigerate your order as soon as you're able to after it's delivered.

Do your brews contain added sugar? Are there any brews suitable for diabetics?

Sugar is part of the fermentation process itself — our cultures consume most of the starting sugar as they ferment, and what remains in the finished bottle is relatively low: kombucha is roughly 2–5% sugar by bottle volume, depending on the brew. Our Original Milk Kefir is made with just two ingredients (full cream milk and kefir cultures) and has no added sugar beyond what's naturally in the milk.

We're not able to make specific recommendations for diabetics or other medical dietary needs — our products are not medicine and aren't intended to diagnose, treat, or manage any health condition. If you're managing diabetes or another condition, please check with your doctor before adding kombucha or kefir to your diet, and consider our lower-sugar or unflavoured options if you do.

Are Kefir and Kombucha Halal?

Like all fermented foods, both kombucha and milk kefir naturally produce a small amount of alcohol as a by-product of fermentation — typically well under 0.5% ABV, similar to what's found in foods like ripe fruit, bread, or fruit juice. Our products are not currently Halal-certified.

If Halal certification is important to you, we'd encourage you to make your own informed decision based on this information, or to check with your own religious guidance, before consuming our products.

How do I prevent my brews from overflowing?

Overflow happens when natural carbonation builds up faster than usual — almost always because a bottle was stored warmer than our ideal 2–4°C. A few simple habits prevent it:

  • Refrigerate your brews as soon as you receive them, ideally at a consistent 2–4°C (see our Storage FAQ for full guidelines).
  • Never store in a wine chiller/wine room — these run warmer (~10–15°C) and cause rapid gas buildup.
  • Chill bottles thoroughly before opening, especially if a cap looks bulging or distended.
  • Never shake a bottle vigorously before opening.
  • Open slowly and with care over a sink, ideally enclosed in a plastic bag if the cap is very distended, to catch any spray.
Do not attempt to open chia-seed kombucha or any bottle with a heavily distended cap — please discard these safely instead, as they are likely to spray.
Is this normal? My Kombucha is fizzy!

Yes, this is completely normal. Unlike pasteurised, shelf-stable brands, our kombucha is raw, unpasteurised, and intentionally prepared fresh and flat at the point of delivery. The live cultures continue to respire and produce natural carbonation over time — how fizzy your bottle becomes depends entirely on how it's been stored after delivery (warmer storage = more fizz, faster). See our Storage FAQ for full guidelines on keeping it at your preferred fizziness.

Is this normal? My kombucha is not fizzy!

Yes, completely normal. Our kombucha is prepared and delivered flat by design, since it's a raw, living product rather than an artificially carbonated one. If you'd like more fizz, simply leave the bottle at room temperature for a little longer, or store it slightly warmer than our ideal 2–4°C fridge setting (check in periodically, as this will speed up carbonation) — see our Storage FAQ for details.

Is this normal? My Kombucha (with chia seeds) / Kefir is clumpy.

Yes. For chia-seed kombucha, our production team fills chia by hand, and static can leave some seeds clumped at the neck or sides of the bottle — this isn't a leak or a safety issue. Simply shake gently to mix; chia is fine to consume whether clumped, wet, or dry.

For milk kefir, natural clumping (curds forming in the liquid) is a normal part of live culture activity, especially if the bottle has been undisturbed for a while. Give it a gentle shake before drinking to recombine.

Is this normal? My Milk Kefir separated into 2 layers / is runny

Yes, very normal. This is a normal sign of an active, live culture — milk kefir is naturally made up of a thicker layer (curd) and a thinner, more liquid layer (whey). 

In fact, this is what we look out for to determine that the milk has been fully fermented. This does not mean the product has gone bad. Simply shake gently to recombine before drinking. As a heads up, when left undisturbed in the fridge, kefir separation will result with time.

The consistency of kefir varies from batch to batch and even within the same batch. It can be range from viscous thick to thiner than milk. This is not an indicator that it has spoiled. The low pH of kefir keeps it from going bad quickly (unlike milk) and contributes to its long shelf life of 4-6 weeks.

Is this normal? My Kefir is fizzy!

Yes. Like our kombucha, milk kefir is a raw, living product, and its live cultures continue to ferment after delivery. Fizziness simply means fermentation has progressed further, usually because the bottle spent more time at room temperature or a warmer fridge setting than our ideal 2–4°C.

It remains safe to drink — chill thoroughly and open with care, without shaking, as described in our Storage FAQ.

Are food grade, BPA-free PET bottles safe: to use / reuse / transport / placed outside my delivery address?

Yes. PET has been extensively tested, with no significant evidence of harmful chemical migration from the plastic into the contents. PET is approved for both single-use and repeat-use as a drink container by the FDA, the European FSA, Singapore SFA and other health and safety agencies worldwide.

Can I freeze my Kombucha / Kefir?

Yes. The viability, nutritional properties remain unchanged and the brews are safe to consume. There is no texture change for freezing kombucha.

For kefir, freezing causes dense clumping that can only be smoothed out only with a blender. Even after blending, the consistency will also be runnier than before freezing.
